The bindings, just like the driver, are quite limited, e.g. do not support regulator supplies. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Rob Herring --- Changes since v6: 1. Drop clock-lanes property. Changes since v5: 1. None Changes since v4: 1. Add clock-lanes, 2. Add Rob's review, 3. Add one more example and extend existing one, 4. Add common clock properties (assigned-*). Changes since v3: 1. Document also two lane setup. Changes since v2: 1. Remove clock-frequency, add reset GPIOs, add supplies. 2. Use additionalProperties. Changes since v1: 1.
